Renal System Questions and Answers Questions
Question 1 of 5
A patient with dysthymia is being treated. The nurse understands that dysthymia differs from major depression in that it:
Correct Answer: B
Rationale: Dysthymia involves chronic, mild depressive symptoms lasting at least two years.
Question 2 of 5

Question 3 of 5
Match the description 'Passively permeable to water under ADH stimulation' to the structure: A) proximal convoluted tubule, B) descending limb of the nephron loop, C) collecting duct, D) ascending limb of the nephron loop.
Correct Answer: C
Rationale: The collecting duct (C) becomes water-permeable with ADH via aquaporin-2, concentrating urine. The proximal tubule (A) and descending limb (B) are always permeable, and ascending limb (D) is not, making C the ADH-dependent match.
Question 4 of 5
If you took a drug that inhibited the reabsorption of Na⺠in the PCT, you would:
Correct Answer: A
Rationale: Inhibiting Na⺠reabsorption in the PCT (A) reduces water reabsorption, increasing urine output (diuresis). Decreased output (B) contradicts this, and bilirubin (C) or fat (D) effects are unrelated to sodium, making A correct.
Question 5 of 5
Urine with a high concentration of C₆Hâ‚â‚‚O₆ is:
Correct Answer: D
Rationale: C₆Hâ‚â‚‚O₆ (glucose) in urine (D) is abnormal (glycosuria) as it's filtered and reabsorbed, not secreted, unless the threshold is exceeded (e.g., diabetes). Normal (A, B) or secreted (C) options misalign, making D correct.
